In politics, money can be a pretty good stand-in for enthusiasm. And the donations pouring in to the Democratic fundraising platform ActBlue since Ruth Bader Ginsburg’s death indicate there is a lot of energy and money on the left.

According to the constantly-ticking tracker on ActBlue’s website, in the hours from 9 p.m. ET, when the news of Ginsburg’s death became widely known, to 9 a.m. ET on Saturday, nearly $31 million was donated to Democratic candidates and causes. The number keeps rising by thousands every second.
